摘　　要：天蒙旅游区人行索桥是主跨420 m的单跨吊悬索桥,主梁长度居世界第一位。该桥宽跨比1:120,梁高52 cm,梁高、宽跨比相比已建成的悬索桥,均处于极低的水平。为解决结构的抗风稳定问题,与常规的双主缆悬索桥不同,本项目采用四根缆索的空间索网体系。本文详细介绍了索桥缆索系统的设计情况,希望为类似项目提供参考。The pedestrian suspension bridge in Tianmeng tourist area is a single span suspension bridge with main span of 420 m,and the length of main girder ranks first in the world.The width-span ratio of the bridge is 1:120,and the girder height is 52 cm.Compared with the existing suspension bridges,the width-span ratio and girder height are at a very low level.In order to solve the problem of wind-resistant stability of the structure,the bridge adopts a space cable network system of four cables,which is different from the conventional double main cables suspension bridges.This paper introduces the design of the cable system of the pedestrian suspension bridge in detail,hoping to provide some reference for similar projects.
